This range of linear quartz infrared heating elements was designed for applications requiring a very fast thermal response and/or high power density with peak emission wavelengths in the short wave range (~1.0-1.2µm). The standard halogen element is available in 3 sizes – models QHL, QHM and QHS. All heaters are fitted with the industry standard R7s type termination which, when used with a suitable R7s holder at both ends, is used to mount the heater and provide the electrical connection. Bespoke sizes are also available but a minimum order of 25 pieces applies.
